Ripley and Call

It's because you're always thinking about that goddamn alien clone fucking her robot girlpet

Coolest ship dynamic is what if a robot and a half alien clone of a government-classified historical figure had a visibly 20-something year age gap and the height difference of a mountain and a mouse. Oh and then you have the deep thematic exploration of being seen as inhuman and feeling like you don't count as human and being unable to reconcile that with simultaneously feeling very human things. Oh and also the robot intended to act as a mercenary but quit that objective the literal second they actually met. Traded it for instant sexual tension and kinship intermixed with like a tiny little bit of weariness and fright.
